Hormone-induced spawning of the spotted rose snapper Lutjanus guttatus was studied using wild and cage-grown fish. Carp pituitary suspension (CPS) and human chorionic gonadotropin (hCG) were assessed. Wild females (0.7–2.1 kg body weight (BW), n = 18) were collected by hook and line in the Gulf of N...

Se estudio la inducción hormonal al desove del pargo manchado Lutjanus guttatus utilizando peces silvestres y peces criados en jaulas flotantes. Las hormonas utilizadas fueron la suspensión de pituitaria de carpa (SPC) y la gonadotropina coriónica humana (GCh). Las hembras silvestres (0.7–2.1 kg de peso corporal (PC), n = 18) se capturaron mediante el uso de anzuelos y línea de fondo en el Golfo de Nicoya, Costa Rica, y fueron inducidas a la maduración final y ovulación en el laboratorio. En el primer experimento, se evaluaron cinco dosis de SPC y el desove se observó con las dosis más altas (4.0 y 4.5 mg SPC kg–1 PC). Las dosis que se aplicaron fueron más bajas que las utilizadas para otras especies de lutjánidos en condiciones similares. En el segundo experimento, se realizó una comparación entre los protocolos utilizados para SPC y GCh con peces criados en jaulas flotantes (n = 30 hembras, 462–995 g; n = 60 machos, 400–600 g); la producción de huevos fue más consistente para el protocolo de la GCh. En el tercer experimento y con peces criados en jaulas flotantes (n = 12 hembras, 368–977 g; n = 24 machos, 400–600 g), se utilizaron dos inyecciones sucesivas con diferentes dosis de GCh para medir la respuesta de las hembras a la GCh y la fertilidad de los huevos desovados. Los experimentos confirman que dos dosis sucesivas de 900 y 700 UI kg–1 PC resultan en un número mayor de huevos desovados y mejores porcentajes de fertilización. |
